DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1 and 2, a voice-controlled vibration electric bed 10 in accordance with the present invention is shown. The voice-controlled vibration electric bed 10 comprises a bed frame 11, a power supply unit 21, a driver 31, a control device 41, at least one microphone 51, and a vibration device 61.

The bed base 11 comprises a base support frame 12, and at least one movable frame 14 mounted at the base support frame 12.

The power supply unit 21 is mounted in the bed base 11 for being electrically connectable to an external AC power source 26 to convert an AC power supplied from the external AC power source 26 into a converted power. In this embodiment, the external AC power source 26 is city power supply, and the converted power supply can an AC power supply having a voltage different from the city power supply, or a DC power supply.

The driver 31 is mounted in the bed base 11 and electrically connected to the power supply unit 21 for driving the at least one movable frame 14 to move relative to the base support frame 12.

The control device 41 is electrically connected to the power supply unit 21 and the driver 31, comprising a microcomputer 42 adapted to provide arithmetic and control functions.

The at least one microphone 51 is mounted in the bed base 11 and electrically connected to the microcomputer 42. The number of the at least one microphone 51 can be one single. Alternatively, multiple microphones 51 can be used and installed in the bed base 11 at different locations. Further, each microphone 51 can be a regular microphone, a directional microphone or a microphone array. In the example shown in FIG. 1, multiple microphones 51 are installed in the bed base 11.

The vibration device 61 is installed in the bed base 11 and electrically connected to the power supply unit 21. Further, the vibration device 61 can be electrically connected to the control device 41 either directly or indirectly. In this embodiment, the vibration device 61 comprises a vibration motor 62 and a vibration pad 64. Further, the vibration device 61 is electrically connected to a driving circuit 66, which is electrically connected to the microcomputer 42. Thus, the vibration device 61 is electrically connected to the microcomputer 42 in an indirect manner. Further, it is to be noted that this arrangement is not a limitation, i.e., the vibration device 61 can also be directly electrically connected to the microcomputer 42. Preferably, an optimal arrangement of the vibration device 61 is to mount the vibration pad 64 at the movable frame 14 and disposed between the mattress (not shown) and the movable frame 14, enabling vibrational energy to be effectively and significantly transferred to the user lying on the mattress. It's worth mentioning that other vibrating source, for example, woofer, can also be used with the vibration pad 64 to substitute for the vibration motor 61, achieving the same vibrational energy transfer effect.

The microcomputer 42 is adapted to recognize the sound picked up by the microphone 51, and to control the vibration device 61 subject to a predetermined frequency range of sound. In actual practice, the microcomputer 42 has set therein a threshold value. When the relationship between the frequency of the sound picked up by the microphone 51 and the set threshold value meets a predetermined vibration condition, the microcomputer 42 controls the vibration device 61 to vibrate. Further, the vibration generated by the vibration device 61 subject to the control of the microcomputer 42 is judged to be a sound synchronization that complies with the vibration condition. This sound synchronization means that the duration of the vibration is equal to the length of time in which the sound continues, and the vibration is started or ended when the sound is started or ended. Further, during application of the present invention, the microcomputer 42 can be set to control the vibration amplitude of the vibration device 61 subject to the volume of the sound picked up by the microphone 51, i.e., the larger the vibration amplitude the louder the sound.

The aforesaid vibration condition is: the frequency of the sound is smaller than the threshold value.

After understanding of the architecture of the voice-controlled vibration electric bed 10, the operation of the voice-controlled vibration electric bed 10 is outlined hereinafter.

Referring to FIGS. 2 and 3 again, when the user is lying on the voice-controlled vibration electric bed 10 and listing to music, or watching a movie or television program, the microphone 51 picks up the sounds of the music or movie or the environmental sounds (such as the voices of the family or the family pet sounds) for judgment by the microcomputer 42. If the sound picked up by the microphone 51 corresponds to a specific frequency, for example, if the frequency of the sound is below the threshold value, it is judged to be in compliance with the vibration condition. At this time, the microcomputer 42 controls the vibration device 61 to synchronously generate corresponding vibrations. The user will feel that there is a relationship between the vibration of the voice-controlled vibration electric bed 10 and the sound he or she heard, or the vibration of the voice-controlled vibration electric bed 10 goes interactive with the sound he or she heard, thereby increasing the fun.

Further, in addition to the aforesaid correlation between the vibration of the voice-controlled vibration electric bed 10 and the sound picked up by the microphone 51, the microcomputer 42 can control the vibration amplitude of the vibration device 61 subject to the volume of the sound picked up by the microphone 51, enhancing fun.

It is to be noted that the vibration condition defined in the aforesaid example that the frequency of the sound is smaller than the threshold value is not a limitation. In other examples, the vibration condition can be selectively defined to be: (1) the frequency of the sound is greater than the threshold value; (2) the frequency of the sound is equal to the threshold value; (3) define a first threshold value and a second threshold value where the first threshold value is smaller than the second threshold value and the sound is judged to be in compliance with the vibration condition if the frequency of the sound is smaller than the first threshold value or greater than the second threshold value.

In conclusion, the invention is characterized by: picking up surrounding sounds by means of a microphone or microphones and then generating corresponding vibrations to interact with the surrounding sounds.
